Instruments for NPP's MSSGL «АZOT-16»

АZOT-16

The monitoring system of steam generator leaks MSSGL «АZOT-16» for a continuous control of leak values of the coolant from the first circuit to the second by the means of registration of gamma radiation of the isotope 16N in the live steam.

PURPOSE

The monitoring system of steam generator leaks MSSGL «АZOT-16» is designed for a continuous control of leak values of the coolant from the first circuit to the second by the means of registration of gamma radiation of the isotope 16N in the live steam.

The system secures the following:

The system is realized on the basis of devices of definition of steam generator leaks upon 16N "UDPP-01"AKP"
